atroni [7]

Answer: 63.59cm²

Step-by-step explanation:

The area covered by the pitch will be gotten by finding the value of the area of the circle and this will be:

Area of q circle = πr²

where,

π = 3.14

r = radius = diameter/2 = 9cm/2 = 4.5cm

Area = πr² = 3.14 × 4.5²

= 3.14 × 20.25

= 63.59cm²

Therefore, the area covered by the pitch is 63.59cm²
